I am new to restoring 300'S, but am in the process of a frame off restoration of a 58 for my son -in-law. I believe the 58 A/C/heater unit in simular to the 57. I also had a hard time removing the unit, and the service manual is not much help. First remove all attaching hardware from the A/C heater unit from the front side of the firewall. Remove the pressure and return lines from the hydraulic actuator. Below the actuator on the inside of the firewall there should be a plate that is attached to the firewall by 4 ( I think) fasteners. After removing the fasteners it will be necessary to slowly pry the plate from the firewall as it is mounted with the factory caulking. Now remove the A/C/heater unit from the firewall side by rolling the top side forward and lifting up and out. I did not remove the actuator before removing the unit, but that may make removal easier. ----- Original Message ----- From: <john_nowosacki@xxxx> To: <Chrysler300@xxxxxxxxxxxxxxx> Sent: Friday, March 14, 2003 3:22 PM Subject: [Chrysler300] Help with 57 dashboard/ a/c unit > Help!! > I thought I was pretty good mechanically, and have restored many cars, but never a 57. > How do I remove the A/C unit from the firewall inside the engine compartment? There is one sentence in the manual that means nothing to me, "From inside the passenger compartment, remove the hydraulic actuator piston, bracket and operating linkage. I think I know what that (they) are, but can't see how they are attached unless it's via crazy glue at the factory. > I thought it would be easier to see if I removed the heater control bezel and radio+radio and ash tray bezel, but I can't seem to locate the hidden spot welds that seem to have that affixed to the dash. > I really like the car and am attempting a 'body-off' resto, so there's no engine in my way on the firewall side, and no front seat in my way in the body of the car, so it "couldn't" be any easier, but I'm stumped. > I'd like to do this without chain saws and torches, since I plan to drive the car someday, but the frustration level is pretty high. Any help would be appreciated (or maybe a pint of Jack Daniels). > Thanks, > John > > To send a message to this group, send an email to: > Chrysler300@xxxxxxxxxxxxxxx > > For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm > > To unsubscribe from this group, send an email to: > Chrysler300-unsubscribe@xxxxxxxxxxxxxxx > > > > Your use of Yahoo!
